MICROPOWER, ULTRA-SENSITIVE

HALL-EFFECT SWITCH

The A3212 integrated circuit is an ultra-sensitive, pole independent Hall-

effect switch with a latched digital output. This sensor is especially suited for

operation in battery-operated, hand-held equipment such as cellular and

cordless telephones, pagers, and palmtop computers. A 2.5 volt to 3.5 volt

operation and a unique clocking scheme reduce the average operating power

requirements to less than 15 µW with a 2.75 volt supply.

Package Suffix ‘LH’ Pinning

(SOT23W)

Unlike other Hall-effect switches, either a north or south pole of sufficient

strength will turn the output on; in the absence of a magnetic field, the output is

off. The polarity independence and minimal power requirement allow these

devices to easily replace reed switches for superior reliability and ease of

manufacturing, while eliminating the requirement for signal conditioning.

Improved stability is made possible through chopper stabilization (dynamic

offset cancellation), which reduces the residual offset voltage normally caused

by device overmolding, temperature dependencies, and thermal stress.

This device includes on a single silicon chip a Hall-voltage generator,

small-signal amplifier, chopper stabilization, a latch, and a MOSFET output.

Advanced BiCMOS processing is used to take advantage of low-voltage and

low-power requirements, component matching, very low input-offset errors,

and small component geometries.

Three package styles provide a magnetically optimized package for most

applications. Package suffixes 'EH' and ‘LH’ are for miniature low-profile

(leadless and leaded, respectively) surface-mount packages while suffix ‘UA’ is

for a three-lead SIP for through-hole mounting.

Caution: These CMOS devices have input

static protection (Class 3) but are still

susceptible to damage if exposed to

extremely high static electrical charges.

Always order by complete part number: the prefix ‘A’ + the basic four-digit

part number + the suffix ‘E’ or 'L' to indicate operating temperature range + a

suffix to indicate package style, e.g., A3212ELH .
